Mobile terminal and program executed therein

ABSTRACT

A CPU of a mobile telephone can carry out both a standby operation for monitoring an incoming call addressed to the mobile telephone and an image processing operation for processing an image captured by a camera. When a camera-dedicated mode is selected, the standby operation is prohibited during an image capture operation of the camera. When the image captured by the camera is processed, negative effects of the standby operation on the process of the image captured by the camera can be avoided. In this manner, the image captured by the camera can be smoothly, appropriately processed, enhancing the operability of the mobile telephone.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a mobile terminal that has telephoniccommunication capability and includes a control means, which carries outboth a standby operation for monitoring an incoming call and an imageprocessing operation for processing an image captured by an imagecapture means. The present invention also relates to a program executedin such a mobile terminal.

2. Description of Related Art

A mobile telephone having a camera is known as one type of mobileterminals. Such a mobile telephone is capable of transmitting an imagecaptured by the camera along with an e-mail message. The mobiletelephone is also capable of displaying the captured image as a standbyscreen image or an incoming call notification screen image on itsdisplay. These features enhance the entertainment value of the mobiletelephone. In order to reduce a cost of the mobile telephone, the mobiletelephone can have one CPU (Central Processing Unit) that carries outboth a standby operation for monitoring an incoming call and an imageprocessing operation for processing the image captured by the camera.More specifically, as shown in FIGS. 7A and 7B, the CPU can conduct thestandby operation at predetermined time intervals, which are defined bya corresponding communication standard. Furthermore, the CPU can conductthe image processing operation for processing the captured image at thetime periods, during which the standby operation is not conducted.

When a state of a radio environment around the mobile telephone isrelatively good, the time required for searching a paging channelbecomes relatively short, and thus the time required for conducting thestandby operation becomes relatively short. On the other hand, when thestate of the radio environment is relatively bad, the time required forsearching the paging channel becomes relatively long, and thus the timerequired for conducting the standby operation becomes relatively long.As a result, in the above arrangement where the one CPU carries out boththe standby operation and the image processing operation, when the stateof the radio environment changes from the relatively good state to therelatively bad state, the time required for the standby operationbecomes relatively long. In such a case, the standby operation cannot befinished when the image processing operation needs to be started (see t1and t2 in FIG. 7B).

In the above arrangement where the CPU cannot simultaneously carry outboth the standby operation and the image processing operation, when thestandby operation is not finished at the time of starting the imageprocessing operation, the image processing operation cannot be startedif priority of the standby operation is higher than that of the imageprocessing operation. This causes removal of some image frames, causinga reduction in the number of the image frames. Thus, image capturingperformance of the mobile telephone is disadvantageously reduced.Furthermore, even if the CPU is capable of simultaneously carrying outboth the standby operation and the image processing operation,performance of the CPU dedicated for the image processing operation isreduced since the CPU needs to sprit its performance between the standbyoperation and the image processing operation. Thus, the performance ofthe CPU dedicated for the image processing operation is reduced, andthus the number of the image frames is reduced. This causes a reductionin the image capturing performance of the mobile telephone.

SUMMARY OF THE INVENTION

The present invention addresses the above disadvantages. Thus, it is anobjective of the present invention to provide a mobile terminal that iscapable of appropriately processing an image captured by an imagecapture means, thereby improving operability of the mobile terminal. Itis another objective of the present invention to provide a program ofsuch a mobile terminal, which enables appropriate process of the imagecaptured by the image capture means, thereby improving the operabilityof the mobile terminal.

DETAILED DESCRIPTION OF THE INVENTION

A mobile telephone (mobile terminal having telephonic communicationcapability) according to an embodiment of the present invention will bedescribed with reference to FIGS. 1 to 6.

With reference to FIGS. 2A and 2B, the mobile telephone 1 has a mainbody 2. A microphone 3 for inputting outgoing voice audio, a speaker 4for outputting incoming voice audio, a display 5 (notification means ofthe present invention), a key pad 6 and an LED (Light Emitting Diode) 7for notifying an incoming call by flashing are arranged at a front sideof the main body 2, as shown in FIG. 2A. The key pad 6 has various keys.These keys include a “CALL START” key, a “CALL END” key, a “REDIAL” key,scroll keys, numeral keys including “0”-“9” keys and the others.

A sounder 8 for outputting a ringer sound (including a ringer melody), acamera 9 (image capture means of the present invention) and a mirror 10are arranged at a rear side of the main body 2, as shown in FIG. 2B. Anantenna 11 is arranged at a top side of the main body 2. The camera 9includes a CMOS (Complementary Metal Oxide Semiconductor) image sensor.

When a user of the mobile telephone 1 wants to capture an image of atarget object other than the user himself, the user holds the mobiletelephone 1, for example, with his hand and directs the camera 9 towardthe target object, so that the image of the target object is displayedon the display 5. This allows the user to check the image of the targetobject to be captured by the camera 9. Alternatively, if the user wantsto include himself as part of his target object to be captured by thecamera 9, the user directs the camera 9 of the mobile telephone 1 towardhimself, so that the image of the user to be captured by the camera 9 isdisplayed on the mirror 10. This allows the user to check the image ofthe target to be captured by the camera 9.

With reference to FIG. 1, in the mobile telephone 1, a CPU 12 (acting asa radio environment measurement means and also a control means of thepresent invention), which includes a microcomputer, is electricallyconnected to a telephone circuit 13 for conducting a telephoneoperation, a ROM (Read Only Memory) 14 that stores a control program(program of the present invention), the microphone 3, the speaker 4, thedisplay 5, the keypad 6, the LED 7, the sounder 8, the camera 9 and themirror 10.

Once the mobile telephone 1 is powered or activated, the CPU 12 conductsa standby operation at predetermined time intervals, which are definedby a corresponding communication standard. Furthermore, when the CPU 12detects activation of an image capture key on the keypad 6, the CPU 12conducts an image processing operation for processing the image capturedby the camera 9 at the time periods, during which the standby operationis not conducted.

In the standby operation, the CPU 12 monitors whether an incoming calladdressed to the mobile telephone 1 is present by searching a pagingchannel of the incoming radio signal, which is transmitted from the basestation 15 and is received by the telephone circuit 13. If the incomingcall addressed to the mobile telephone 1 is detected, the CPU 12 outputsa flash initiation command to the LED 7 to initiate flashing of greenlight from the LED 7 and also outputs an output initiation command tothe sounder 8 to initiate output of the ringer sound from the sounder 8.Furthermore, if a caller telephone number is transmitted from the basestation 15, the CPU 12 outputs a display initiation command to thedisplay 15 to initiate the display of the caller telephone numbertransmitted from the base station 15.

The telephone circuit 13 outputs an RSSI (Received Signal StrengthIndicator) output to the CPU 12. The RSSI output indicates a strength ofthe signal received from the base station 15. When the CPU 12 receivesthe RSSI output from the telephone circuit 13, the CPU 12 determines acurrent state of the radio environment by analyzing the RSSI output.

Next, the operation of the above arrangement will be described withreference to FIGS. 3 to 6 in conjunction with FIGS. 1 and 2. First, whenthe CPU 12 detects that the keypad 6 is operated to select an operationmode from “a camera-dedicated mode”, “a camera-dedicated mode under abad radio environment” and “a camera/telephone bifunctional mode” while“a mode selection menu”, such as one shown in FIG. 3A, is displayed onthe display 5, the CPU 12 sets a corresponding one of “thecamera-dedicated mode”, “the camera-dedicated mode under the bad radioenvironment” and “the camera/telephone bifunctional mode” based on theoperation of the keypad 6.

Then, when the CPU 12 detects activation of the image capture key on thekeypad 6 for capturing the image of the target object, the CPU 12conducts an image capture operation shown as a flowchart in FIG. 4. Inthis operation, the CPU 12 first determines the current operation mode(steps S1 and S2). If the CPU 12 detects that the current operation modeis “the camera-dedicated mode”, “YES” is returned at step S1, and theCPU 12 shifts the operation to the image capture operation in thecamera-dedicated mode (step S3). On the other hand, if the CPU 12detects that the current operation mode is “the camera-dedicated modeunder the bad radio environment”, “NO” is returned at step S1, andcontrol moves to step S2 where “YES” is returned. Then, the CPU 12shifts the operation to the image capture operation in “thecamera-dedicated mode under the bad radio environment” (step S4).Furthermore, if the CPU 12 detects that the current operation mode is“the camera/telephone bifunctional mode”, “NO” is returned at both stepsS1 and S2, and the CPU 12 shifts the operation to the image captureoperation in “the camera/telephone bifunctional mode” (step S5).

Among the above-described operations, the image capture operation in“the camera-dedicated mode” and the image capture operation in “thecamera-dedicated mode under the bad radio environment” will be describedbelow.

(1) Image Capture Operation in “the Camera-dedicated Mode”

First, the image capture operation in “the camera-dedicated mode” willbe described with reference to a flowchart shown in FIG. 5. When theoperation is changed to initiate the image capture operation in “thecamera-dedicated mode”, the CPU 12 outputs an image capture command tothe camera 9 to initiate the image capture operation through the camera9 (step S11). Then, the CPU 12 prohibits the standby operation (stepS12) and outputs a display command to the display 5 to display pixels ofa camera icon (indicated by “R”) on the display 5, as shown in FIGS. 3Cand 3E (step S13, conducting a first notification operation of thepresent invention).

At this stage, if pixels of an antenna bar icon or of a signal strengthmeter icon (indicated by “P”) has been displayed on the display 5 basedon the current state of the radio environment, as shown in FIG. 3B, theCPU 12 clears the pixels of the antenna bar icon and displays the pixelsof the camera icon and pixels of “OUTSIDE” (indicated by “Q”) on thedisplay 5, as shown in FIG. 3C. The “OUTSIDE” indicates that the mobiletelephone 1 is currently outside the coverage area. Alternatively, ifthe pixels of “OUTSIDE” have been already displayed on the display 5according to the current state of the radio environment, as shown inFIG. 3D, the CPU 12 also displays the pixels of the camera icon inaddition to the pixels of “OUTSIDE”, as shown in FIG. 3E.

Next, the CPU 12 monitors whether an image capture operation terminationkey on the keypad 6 has been activated to terminate the image captureoperation (step S14). If the CPU 12 detects that the image captureoperation termination key has been activated, “YES” is returned at stepS14. Then, the CPU 12 outputs an image capture operation terminationcommand to the camera 9 to terminate the image capture operation throughthe camera 9 (step S15). Next, the CPU 12 enables the standby operation(step S16) and outputs a camera icon clear command to the display 5 toclear the pixels of the camera icon on the display 5 (step S17,conducting a second notification operation of the present invention).Furthermore, the CPU 12 commands the display 5 to display the pixels ofthe antenna bar icon or the pixels of “OUTSIDE” depending on the currentstate of the radio environment.

According to the above control operation, by setting “thecamera-dedicated mode” in advance, the user of the mobile telephone 1can capture the image of the target object upon prohibiting the standbyoperation of the mobile telephone 1 in “the camera-dedicated mode”.Furthermore, when the user recognizes the pixels of the camera icondisplayed on the display 5, the user can notice that the standbyoperation of the mobile telephone 1 is prohibited to disable acceptanceof the incoming call.

(2) Image Capture Operation in “the Camera-dedicated Mode under the BadRadio Environment”

Next, the image capture operation in “the camera-dedicated mode underthe bad radio environment” will be described with reference to aflowchart shown in FIG. 6. When the operation is changed to initiate theimage capture operation in “the camera-dedicated mode under the badradio environment”, the CPU 12 outputs an image capture command to thecamera 9, so that the camera 9 initiates the image capture operation(step S21). Then, the CPU 12 determines the current state of the radioenvironment based on the RSSI output received from the telephone circuit13 (step S22). Furthermore, the CPU 12 monitors whether the imagecapture operation termination key on the keypad 6 has been activated(step S23).

When the CPU 12 detects that the received signal strength indicated withthe RSSI output is less than a predetermined reference signal strength(set as a threshold value), and thus the radio environment is in arelatively bad state (i.e., when a first predetermined condition of thepresent invention is satisfied), “NO” is returned at step S22. Then, theCPU 12 outputs the flash initiation command to the LED 7 to initiateflashing of red light (not the green light) from the LED 7 (step S24).In this case, if the CPU 12 detects the activation of the image captureoperation termination key on the keypad 6, “YES” is returned at stepS23. Then, the CPU 12 outputs the image capture operation terminationcommand to the camera 9 to terminate the image capture operation of thecamera 9 (step S25), so that the image capture operation in thecamera-dedicated mode under the bad radio environment is terminated.

After the CPU 12 commands the LED 7 to initiate the flashing of the redlight (step S24), the CPU 12 monitors whether a camera-dedicated modeselection key for shifting the operation to the camera-dedicated modehas been activated (step S26). Then, when the CPU 12 detects theactivation of the camera-dedicated mode selection key, “YES” is returnedat step S26. Next, the CPU 12 outputs a flash termination command to theLED 7 to terminate the flashing of the red light from the LED 7 (stepS27) and prohibits the standby operation (step S28). Furthermore, theCPU 12 outputs the display command to the display 5 to display thepixels of the camera icon on the display 5 (step S29, conducting thefirst notification operation of the present invention).

At this stage, if the pixels of the antenna bar icon have been displayedon the display 5 based on the current state of the radio environment, asshown in FIG. 3B, the CPU 12 clears the pixels of the antenna bar iconand displays the pixels of the camera icon and pixels of “OUTSIDE” onthe display 5, as shown in FIG. 3C. Alternatively, if the pixels of“OUTSIDE” have been already displayed on the display 5 according to thecurrent state of the radio environment, as shown in FIG. 3D, the CPU 12also displays the pixels of the camera icon in addition to the pixels of“OUTSIDE”, as shown in FIG. 3E.

Furthermore, if the CPU 12 detects that the camera-dedicated modeselection key has not been activated for more than a predetermined timeperiod, “NO” is returned at step S26. Then, the CPU 12 outputs the flashtermination command to the LED 7 to terminate the flashing of the redlight from the LED 7 (step S30) and then returns to steps S22, S23.

Next, after the pixels of the camera icon are displayed on the display 5(step S29), the CPU 12 determines the current state of the radioenvironment based on RSSI output received from the telephone circuit 13(step S31). Furthermore, the CPU 12 monitors whether the image captureoperation termination key on the keypad 6 has been activated toterminate the image capture operation (step S32).

At this stage, if the CPU 12 detects that the received signal strengthis equal to or greater than the reference signal strength and therebythe radio environment has changed from the relatively bad state to therelatively good state (i.e., if a second predetermined condition of thepresent invention is satisfied), “YES” is returned at step S31. Then,the CPU 12 enables the standby operation (step S33) and outputs thecamera icon clear command to the display 5 to clear the pixels of thecamera icon (step S34, conducting the second notification operation ofthe present invention). Furthermore, the CPU 12 commands the display 5to display the pixels of the antenna bar icon or the pixels of “OUTSIDE”depending on the current state of the radio environment.

In this case, if the CPU 12 detects the activation of the image captureoperation termination key on the keypad 6, “YES” is returned at stepS32. Then, the CPU 12 enables the standby operation (step S35) andoutputs the camera icon clear command to the display 5 to clear thepixels of the camera icon (step S36). Furthermore, the CPU 12 commandsthe display 5 to display the pixels of the antenna bar icon or thepixels of “OUTSIDE” depending on the current state of the radioenvironment. Then, the CPU 12 outputs the image capture operationtermination command to the camera 9 to terminate the image captureoperation of the camera 9 (step S25), so that the image captureoperation in the camera-dedicated mode under the bad radio environmentis terminated.

According to the above control operation, by setting “thecamera-dedicated mode under the bad radio environment” in advance, theuser of the mobile telephone 1 can recognize that the radio environmenthas changed from the relatively good state to the relatively bad statewhen the LED 7 initiates the flashing, then the user can conduct theimage capture operation upon prohibiting the standby operation of themobile telephone 1 by activating the camera-dedicated mode selectionkey. Furthermore, the user can notice that the standby operation of themobile telephone 1 is prohibited to disable acceptance of the incomingcall when the user recognizes the pixels of the camera icon displayed onthe display 5. Thereafter, when the pixels of the camera icon arecleared from the display 5, the user can recognize that the radioenvironment has changed from the relatively bad state to the relativelygood state and can also recognize that the standby operation of themobile telephone 1 is enabled to allow the acceptance of the incomingcall.

The above description is intended for the case where the user of themobile telephone 1 does not include himself as part of his target objectto be captured by the camera 9, i.e., where the user directs the camera9 toward the target object and captures the image of the target objectthrough the camera 9. In such a case, the display 5 is consequentlydirected toward the user of the mobile telephone 1. Thus, the user canrecognize that the standby operation of the mobile telephone 1 isprohibited when the user recognizes the pixels of the camera icon on thedisplay 5, which are displayed after the selection of the “thecamera-dedicated mode” or after the activation of the camera-dedicatedmode selection key in the camera-dedicated mode under the bad radioenvironment.

As described above, the present embodiment provides the followingadvantages. That is, in the situation where “the camera-dedicated mode”is selected as the current mode, the standby operation of the mobiletelephone 1 is prohibited during the image capture operation through thecamera 9. Thus, when the image captured by the camera 9 is processed,the negative effects of the standby operation on the process of theimage captured by the camera 9 can be avoided. In this manner, the imagecaptured by the camera 9 can be smoothly, appropriately processed,enhancing the operability of the mobile telephone 1.

Alternatively, in the situation where “the camera-dedicated mode underthe bad radio environment” is selected as the current mode, when theradio environment changes from the relatively good state to therelatively bad state during the image capture operation through thecamera 9, the LED 7 initiates the flashing. At this stage, if thecamera-dedicated mode selection key is activated, the standby operationof the mobile telephone 1 is prohibited. Thus, in this case, when theimage captured by the camera 9 is processed, the negative effects of thestandby operation on the process of the image captured by the camera 9can be avoided. In this manner, the image captured by the camera 9 canbe smoothly, appropriately processed. Furthermore, when the radioenvironment changes from the relatively bad state to the relatively goodstate, the standby operation is automatically enabled. Thus, the imagecaptured by the camera 9 can be smoothly, appropriately processed, andit is possible to detect the incoming call addressed to the mobiletelephone 1, allowing acceptance of the incoming call.

Furthermore, when the standby operation is prohibited, the pixels of thecamera icon are displayed on the display 5. Thus, when the user of themobile telephone 1 recognizes the pixels of the camera icon displayed onthe display 5, the user can recognize that the standby operation of themobile telephone 1 is prohibited, and thus the acceptance of theincoming call is disallowed. Furthermore, when the standby operation ofthe mobile telephone 1 is enabled, the pixels of the camera icon arecleared from the display 5. Thus, when the user of the mobile telephone1 recognizes the cleared state of the pixels of the camera icon on thedisplay 5, the user can recognize that the standby operation of themobile telephone 1 is enabled, and thus the acceptance of the incomingcall is allowed.

Furthermore, in this case, the pixels of “OUTSIDE” are displayed on thedisplay 5 in addition to the pixels of the camera icon. Thus, the userof the mobile telephone 1 can recognize that the standby operation isprohibited, and thus the acceptance of the incoming call is disallowedunder the above-described circumstance which is different from thenormal situation where the pixels of “OUTSIDE” are displayed on thedisplay 5 when the mobile telephone 1 cannot receive the signal or isplaced in the bad radio environment.

It should be understood that the present invention is not limited to theabove embodiment, and the above embodiment can be changed or modified inthe following manner.

The mobile terminal is not limited to the mobile telephone and can be apersonal digital assistant (PDA) or the like. Furthermore, the camera isnot necessarily placed on the opposite side of the main body of themobile telephone, which is opposite to the side of the main body wherethe display and the keypad are arranged. That is, the camera can beplaced on the side of the main body where the display and the keypad arearranged. Furthermore, it is not necessary to integrate the camera intothe main body of the mobile telephone. For example, the camera can bedetachably connected to the main body of the mobile telephone through aninterface provided in the mobile telephone for connecting between themobile telephone and the camera.

In the situation where the camera-dedicated mode under the bad radioenvironment is selected, when the radio environment changes from therelatively good state to the relatively bad state, the standby operationcan be automatically prohibited without requiring the activation of thecamera-dedicated mode selection key. Furthermore, when the radioenvironment involved in the standby operation changes from therelatively bad state to the relatively good state, the LED can flashlight of a color other than the green or red to notify the change of theradio environment to the user of the mobile telephone. Then, when thekeypad is operated to change the operation to the camera/telephonebifunctional mode, the standby operation can be enabled.

The first notification operation is not limited to the display of thepixels of the camera icon on the display. For example, the firstnotification operation can be a flashing operation or continuouslighting operation of the LED, a display operation of a predeterminedmessage on the display, the output operation of predetermined sound orpredetermined sound message from the sounder or a combination of theseoperations. Furthermore, another LED can be placed on the side of themain body of the mobile telephone where the camera is arranged. This LEDcan be flashed when the standby operation of the mobile telephone 1 isprohibited by the selection of “the camera-dedicated mode” or by theactivation of the camera-dedicated mode selection key after theselection of “the camera-dedicated mode under the bad radioenvironment”. With the above arrangement, even if the user directs thecamera toward himself, the user can recognize that the standby operationof the mobile telephone 1 is prohibited when the user recognizes theflashing of this LED, which is activated after the selection of the “thecamera-dedicated mode” or after the activation of the camera-dedicatedmode selection key in the camera-dedicated mode under the bad radioenvironment.

The first notification operation can be varied in a continuous manner orin a stepwise manner based on duration time of the relatively bad radioenvironment. For example, when the duration time of the relatively badradio environment exceeds a predetermined time period, the camera iconcan be changed from one form to another form (or among various forms) tonotify the duration of the bad radio environment beyond thepredetermined time period to the user of the mobile telephone.

The control program is not necessarily stored in the ROM by the time ofshipment of the mobile telephone. For example, the control program canbe downloaded to the mobile telephone through a communication networkand can be installed in the mobile telephone upon activation of apredetermined key.

Additional advantages and modifications will readily occur to thoseskilled in the art. The invention in its broader terms is therefore, notlimited to the specific details, representative apparatus, andillustrative examples shown and described.
